Marine Geospatial Ecology Tools (MGET), also known as the GeoEco Python package, is an open source geoprocessing toolbox that includes over 250 tools useful for a variety of tasks. These tasks include downloading popular oceanographic datasets in GIS-compatible formats, identifying fronts and eddies in satellite images, building statistical habitat models from species observations and creating habitat maps, modeling biological connectivity by simulating hydrodynamic larval dispersal, and building grids that summarize fishing effort, catch per unit effort, and other statistics.

They are designed to work wtih ArcGIS.

Among those helping Raleigh to be an open city if not a fully "open-source" city are Esri, SeeClickFix and others. Remember: open source software and open data and open standards are not the same thing. The open gov effort uses Esri's open source GeoPortal (which taps into ArcGIS services) with SeeClickFix (proprietary) supporting Open311 standards.

The Dead Ushahidi site is a bit meta: it documents, on a Crowdmap map (that's the free online tool for anyone to create a crowdsourced map of anything) Crowdmap efforts that are "dead." The "Dead Means Dead" page explains what's needed for a non-dead, aka, useful, Crowdmap, then details what criteria can put an existing map in the dead pool.

To end up in the Ushahidi cemetery, one of the following is true about map:
  • No one (let alone a crowd) has submitted a report to your map in the last 12 months.
  • For time-bound events, like elections and disasters, the number of reports are so infinitesimally small (in relation to the number of the community the map is targeting) that the map never reached a point anywhere near relevance. (Our measure for elections is, for instance, # of submissions / # of registered voters > .0001).
  • The map was never actually started (no category descriptions, fewer than 10 reports). We call that a stillbirth. 
Questions?  Email us: .(JavaScript must be enabled to view this email address). Tweet us at @deadushahidi.  Or just poke around and submit your own Ushahidi corpse.  They are sure to be around. 
Like many Crowdmap implementations this one does not make clear who "we" are or the goal of the map, aka what will be done with the data. I highlighted a similar concern with a map aimed at documenting damage and needs during last year's Hurricane Irene.
